What does it mean for a function to be a source term in fluid dynamics?

[fury902]

I'm relatively knew to fluid dynamics. I'm self teaching myself. Could someone explain what it means to say a function or vector is a source term? Are there any significant mathematical properties/uniqueness's? I'm working with vector matrices, so if you could explain in this context that would be great. Thanks.

Good luck.
